[SOLVED] Redirect to current page?

[galvin]

I want to be able to sometimes redirect users to the CURRENT page, whatever page that may be, rather than actually redirect them to another page.  I have this function below that works fine for truly redirecting, but how can I adjust this code to allow "redirecting" to the CURRENT page?...

 

	function redirect_to($location = NULL ) {
	if($location != NULL) {
		header("Location: {$location}");
		exit;
	}
}

$_SERVER['PHP_SELF']

 

Should work

Or $_SERVER['SCRIPT_URL']
